paris78 feel free to share you forum details so that other q5/sq5 owners can come and see the good work you are doing.
With regards to this forum to be clear this is a User forum not OBD11 Support forum.
Not sure if this will answer your question but I will share the information anyway.
Firstly I would point out that OBD11 Have built the IOS Setup for long coding differently to Android, In my personal opinion Android is superior but its a personal preference.
So in Android you have the Long Coding menu and behind that you have two view.
View 0 (the 0/1 on top of the screen) shows you all the hard coded descriptions that come with the car from VAG
FOR SOME REASON Android displays these names with _ eg xenon_retry and the Status as well eg not_active. IOS Displays them as xenon retry and status as not active
View 1 shows you the Bytes and the Bits, If there are user descriptions then these are either shown against a single Bit or a group of Bits.
If you select any Bit if there is description data then it will show the Name and the various values that some user has input.
Further if there are multi language descriptions then without having to change app or database language you can use the dropdown list and see these other descriptions
For some reason IOS Dev team decided to split the descriptions from the Byte / Bit process.
Further they currently do not give you the option to add / amend or delete these descriptions
So apart from being in a different format it also gets confusing because you and I may both of added a description to a specific byte/bit, in Android you see the first entry but when you hist select you can see all the different setups and can tick as good or bad.
However the way they have build IOS You see all the options together and there is no link to the underlying Byte Bit which I have complained about several times.
In IOS The only way to see descriptions in other languages is by going to settings and changing to different language and going back to view.
Further I am sure you have noticed that in IOS you only have one Language but in Android you have two (Application and Database).
If this does not answer your question then can you give us a bit more detail please.
